docs(config): state data directory behavior positively

Documentation should describe what the software does, not enumerate
what it does not do. Rephrase the data-directory wording around the
positive facts (each directory is independent; a new root starts with
empty state) and drop the "never moves or copies" constructions from
config.md, the config.html env table, and the changeset.

Remove the legacy session archive migration from session daemon startup. Setting `PI_WEB_DATA_DIR` only selects where PI WEB-managed state lives; it never moves or copies existing state, and each data directory is independent. Remove the legacy session archive migration from session daemon startup. Each `PI_WEB_DATA_DIR` data directory is independent: pointing PI WEB at a new data directory starts there with empty registries and no session archives.
You are only affected if you have session archives created before July 2026 in the default `~/.pi-web` data directory and you newly set a custom `PI_WEB_DATA_DIR`. To carry those archives over, stop PI WEB, then copy `archived-sessions.json` and the `archived-sessions/` directory from the old data directory into the new one.
